WARNING!!! Normana is a dangerous suckpuppet.
Please clear up your mind! Is vj1977 my sockpuppet account or am I his sockpuppet account. Or both? Is it a sockpuppet chain or a circle?
51% attack on Byzantium is actually 34%. So in Albatros it's actually not 51%, but 34%, because the security assumption is that at most one third (of selected block producers) is Byzantine.
Haven't heard that, can you provide a proof that 51% is 34%?
There is no 51% attack, that's just a stupid saying from PoW chains. What usually is meant by 51% attack is double-spend attack or selfish mining attacks.
For those attacks, attackers on PoW chains need about 51% of mining power (well, you can do with less than 51%, but then you need luck). As far as I understood, PBFT needs 67% for double-spend, no? And selfish mining is not an issue in Albatross as there is no mining at all.
From what I understood, the thing you can do with 34% in PBFT is to halt the protocol. This attack will cause your 34% stake to become worth nothing and can be resolved by all other stakers through a collaborative fork. So the effect is limited and you don't earn anything from it (= no incentive to perform), definitely not comparable to a 51% attack on PoW chains.
